Problem building rpy in F33

[José Abílio Matos]

Hi,
  I am having troubles build rpy in Fedora 33 and I am running out of ideas.

https://src.fedoraproject.org/rpms/rpy 

An example of a failure is here:
https://koji.fedoraproject.org/koji/taskinfo?taskID=48721928 

The problem says:

error: attempt to use unversioned python, define %__python to /usr/bin/python2 
or /usr/bin/python3 explicitly

But I have no idea where does this comes from. Does anyone have any idea of 
what is going wrong?

Regards,

Hey José Abílio o/

This is https://fedoraproject.org/wiki/Changes/PythonMacroError

And in the spec:

# export PYTHONPATH=%{buildroot}%{python_sitearch}

There are several things at play:

  - %{python_sitearch} is derived from %__python
  - commenting macros like this is not preventing them form being evaluated

See also:

$ rpmlint rpy.spec
rpy.spec:57: W: macro-in-comment %{srcname}
rpy.spec:58: W: macro-in-comment %{buildroot}
rpy.spec:58: W: macro-in-comment %{python_sitearch}

I knew that but I forgot it \o/ since most of the time it is harmless. The 
change that I have applied was to convert to python3_sitearch since I still 
have hope that the tests will work again.

Best regards,

PS: I forgot to send the message... oops. :-)
